Tefal - Clipso Control Plus Pressure Cooker 10L @ Peters Of Kensingtons $261 ($6 delivery)
Stainless, heavy base, 10L and comes with a little detachable beeper to tell you when the cooking time is up.
:-) I love my kitchen bits.....! Dont have one of these but have an ally equivalent which needs replacing.
The delivery is realistic (unless you live in the boonies) - $6 to 2000 but $25 to Perth.
Otherwise selling around $300 mark (except at the pressure cooker centre where they are 269 but the shipping kills the price over Peters)
